• im obviously speaking from my experience, because ive solved many problems but could never level up my kata because i never COMPLETELY solve them

There's no such thing as completely solving a kata. You either do or you don't. If you can't pass all test cases then you simply haven't solved anything, I don't see why one should get points for that.

• because of some dumb case that was never mentioned

They don't really have to be mentioned. You can always print the input and find what they are yourself.

What you are suggesting is, no offense, quite stupid. Firstly, if you want to earn "points by solving a problem based on the number of cases you solved", then what about katas ranked 8 kyu to 5 kyu? Are you saying that CW have to make a 7 kyu kata, with, say, 100 random test cases, worth a 100 points and that CWarriors can earn up to 100 points from solving one low-ranked kata alone? That defeats the purpose of random test cases.They are there to make sure that your code can and will run on all cases stated by the kata. If your code failed to do so, then IMPROVE on it and don't get discouraged.
